SAMMY the seal is back. The intrepid mammal has once again been spotted navigating North Yorkshire's rivers - and has now been captured on film.

Martin Lingard, 33, of Sherburn-in-Elmet, noticed the seal in the River Ouse as he was walking near Stillingfleet, between York and Selby, and filmed him bobbing in the water.

He said: "I was not expecting it, he just popped up. I was going for a walk."

The sighting will add to speculation about the whereabouts of Sammy's home after the seal was spotted in the River Wharfe, in Tadcaster, earlier this month.

But residents of Cawood later claimed the slippery creature, saying Sammy was spotted sunbathing beside the river, in the village, in 2004.

Martin said: "I saw a seal a few years ago at Ryther. People made a thing about it being from Tadcaster the last time, but it has been about for a few years.

"It will be migrating up and down all the time following the fish."

He said the seal he photographed had a distinctive tag on its flipper - the same as that reported on the Cawood seal.
